21 Oct 2012 Glycogen Synthase (GS) is an enzyme present in liver and muscle cells that catalyses the production of glycogen. It catalyses a condensation 


Glycogen synthase kinase 3beta (GSK3beta) is a key component in many biological processes including insulin and Wnt signaling. Since the activation of each signaling pathway results in a decrease in GSK3beta activity, we examined the specificity of their downstream effects in the same cell type. Ins …

Furthermore, glycogen synthase can only add glucoses with an α(1->4) link. For branching to occur, a branching enzyme (specifically, amylo-(1,4->1,6)-transglycosylase is needed. This enzyme can transfer terminal chain segments to the 6-carbon hydroxyl of any glucose in a glycogen chain. 1998-10-01 · The glycogen synthase activity is low or immeasurable in liver biopsies, whereas the liver glycogen content is only moderately decreased. To investigate whether mutations in the GYS2 gene are involved in GSD0, Orho et al. (1998) determined the exon-intron structure of the GYS2 gene and examined 9 affected children from 5 families for linkage of GSD0 to the GYS2 gene, using intragenic and 2014-05-09 · Glycogen is a high molecular mass polysaccharide that serves as a repository of glucose for use in times of metabolic need. Glycogen synthase (EC catalyzes the addition of glucose monomers to the growing glycogen molecule through the formation of alpha-1,4-glycoside linkages (Pederson et al., 2004).

Glycogen synthase

Inactivation of glycogen synthase: cAMP-dependent protein kinase phosphorylates glycogen synthase to make it susceptible to phosphorylation by other protein kinases that phosphorylate and inactivate it. The consequence is that when glycogen breakdown occurs, glycogen synthesis does not occur simultaneously in a futile glycogen breakdown

Acquisition of resistance to gemcitabine is a challenging clinical and biological hallmark property of refractory pancreatic cancer. Here, we investigated whether glycogen synthase kinase (GSK)‐3β, an emerging therapeutic target in various cancer types, is mechanistically involved in acquired resistance to gemcitabine in human pancreatic cancer. Glycogen synthase kinase-3 (GSK3) is a proline-directed serine-threonine kinase that was initially identified as a phosphorylating and inactivating glycogen synthase (see GYS1, 138570).Two isoforms, alpha (GSK3A; 606784) and beta, show a high degree of amino acid homology (Stambolic and Woodgett, 1994).GSK3B is involved in energy metabolism, neuronal cell development, and body pattern Glycogen synthase catalyzes the rate-limiting step of glycogen biosynthesis and has two major isoforms in mammals -- muscle isoform (GYS1) and liver isoform (GYS2) respectively (1). Glycogen synthase kinase-3α (GSK-3α) and glycogen synthase kinase-3β (GSK-3β) phosphorylate glycogen synthase at multiple sites in its C-terminus (Ser641, Ser645, Ser649 and Ser653) inhibiting its activity (2, 3). 2001-04-01 Bachrach BE, Weinstein DA, Orho-Melander M, et al.

First discovered in 1980 as a regulatory kinase for its namesake, glycogen synthase (GS), GSK-3 has since been identified as a protein kinase for over 100 different proteins in a variety of different pathways. Activators of glycogen synthase. PP1 works on glycogen synthase as well as glycogen phosphorylase.

Liver glycogen synthase (GYS2), a key enzyme in glycogen synthesis, is controlled by a complex interplay between the allosteric activator glucose-6-phosphate (G6P) and reversible phosphorylation through glycogen synthase kinase-3 and the glycogen-associated form 2010-12-23 · Canonical Wnt signaling requires inhibition of Glycogen Synthase Kinase 3 (GSK3) activity, but the molecular mechanism by which this is achieved remains unclear. Here, we report that Wnt signaling triggers the sequestration of GSK3 from the cytosol into multivesicular bodies (MVBs), so that this enzyme becomes separated from its many cytosolic substrates.
